illion Credit Score and Report: Everything You Need to Know

Important update on illion: illion was one of Australia's three major credit reporting bureaus, alongside Experian and Equifax. In 2024, Experian acquired illion, and illion's consumer credit data has now been consolidated into the Experian bureau. If you previously had an illion credit score on ClearScore, this is now provided by Experian - and your ClearScore Australia account shows a single Experian credit score and report. The information below explains what illion was and how it worked, and points you to where to find the equivalent information for your Experian credit score today.

Before credit providers or financial institutions approve a new line of credit, they conduct credit checks to understand the risk profile of the borrower. Running a credit check involves reviewing credit reports of borrowers prepared by credit bureaus and credit scores.

Until recently, a large number of lenders in Australia relied on illion credit scores and reports to assess eligibility, alongside Experian and Equifax. Following Experian's acquisition of illion, illion's consumer credit data has been consolidated into the Experian bureau, so lenders that previously checked illion data now access this information through Experian.

Let's take a look at what illion was, how illion credit checks worked, and where this information lives now under Experian.

What was illion?

illion was a credit reporting agency in Australia, and was one of the country's three major credit reporting agencies - alongside Experian and Equifax - until it was acquired by Experian. illion's consumer credit data has now been consolidated into the Experian bureau. In 2014, it became the first credit rating agency in Australia to implement comprehensive credit reporting. illion collected the credit history of businesses and individuals from various credit providers and used its proprietary algorithm to prepare credit reports and calculate credit scores. This data and methodology are now part of the Experian bureau, which uses its own scoring model to calculate your credit score.

What was included in an illion credit report?

An illion credit report included personal details and information about your personal credit history, such as:

• Name, residential address, date of birth, employer and driver's licence number

• Credit history (including credit accounts and hard credit checks), credit limit, and repayment history

• Details of court judgments, bankruptcy proceedings, and any creditor who believed you obtained credit fraudulently or evaded payment obligations

Your Experian credit report - which now includes the consumer credit data previously held by illion - covers the same categories.

Under comprehensive credit reporting (which illion helped pioneer in Australia in 2014, and which Experian continues to use), positive and negative information stays on your report for different lengths of time. Monthly repayment history stays for two years, and bankruptcy filings stay for five years. Hard credit checks remain on your report for five years, regardless of approval status.

illion credit checks: who ran them, and what a credit check looks like now

An illion credit check was simply a request to view the credit information illion held about you. A lender, telco or utility would ask illion for your credit report and score, use that data to judge how risky you were as a borrower, and then approve, decline or price the application accordingly. Following Experian's acquisition of illion, those same organisations now request that consumer credit data through Experian instead, so an "illion credit check" in Australia today is, in practice, an Experian credit check.

Hard vs soft credit checks - which leaves a footprint

Not every credit check is recorded the same way. A hard credit check (also called a credit enquiry) happens when you formally apply for credit, and it is written onto your credit report where other lenders can see it. A soft credit check happens when you view your own credit information, or when a company runs a background or pre-approval assessment that doesn't involve a formal application. Soft checks are visible only to you and never affect your score.

What changed for those checks after the Experian acquisition

Nothing changed about how checks work - only about where the data sits. Organisations that previously subscribed to illion for consumer credit checks now draw on the Experian bureau, and the enquiry history that illion held has been consolidated there too. Your past enquiries did not disappear, and the same ageing rules still apply.

How to find out which bureau a lender uses before you apply

Lenders are not obliged to publish which bureau they use, and many check more than one. The most reliable approach is to read the credit guide or privacy policy on the lender's website, which must name the credit reporting bodies it discloses information to, or simply ask before you apply. Because Australia now has two main consumer bureaus - Experian and Equifax - it is worth knowing both of your scores rather than assuming one number represents you everywhere.

Checking your own score never costs you points

Checking your credit score with ClearScore is a soft check. You can look as often as you like, and it will never appear as an enquiry to a lender or reduce your score. That makes it safe to check before you apply for anything, so you can time an application for when your file is in the best possible shape rather than finding out afterwards.

What was a good illion credit score, and how did it compare with Equifax and Experian?

Credit scores have historically differed between illion, Experian, and Equifax because each used its own proprietary scoring model. Now that illion's consumer credit data has been consolidated into Experian, your scores may still differ between Experian and Equifax for the same reason - each uses its own model.

It was common for an Equifax score and an illion score to be different - and the same is true today between your Experian score and your Equifax score, since each bureau uses its own scoring model. illion's credit score ranged from 0 to 1,000, with a score of 500 to 699 considered good. On ClearScore Australia today, your Experian credit score is shown on a 0 to 1,000 scale, with 500 to 699 falling in the 'On good ground' band under ClearScore Australia's band labels for Experian data. A high score indicates lower credit risk. A 'Good' score on your Experian credit file (the data previously held by illion has been consolidated here) shows there is no significant negative information on your file, or that there isn't yet enough information to calculate a higher score.

Here's how illion's score bands compared to Experian and Equifax historically, alongside the credit score bands now used on ClearScore Australia (Experian, scale 0-1,000):

Where can I see my credit report now?

Today, you can access your Experian credit score and report - which now includes the consumer credit data previously held by illion - for free, forever, using ClearScore. Sign up to ClearScore by following the steps below:

• Visit the ClearScore Australia website to start your sign up for free.

• Create a ClearScore account by entering your personal information, such as your name, date of birth, and email address.

• Verify your identity by providing additional information, such as your address and ID.

• Once you have verified your identity, you will be able to see your credit score and report on the ClearScore dashboard.

• Then, simply head to your ClearScore report page to view your Experian credit score and report. (illion is no longer shown as a separate tab - its data is now consolidated into your Experian credit score.)

illion login and account questions after the Experian acquisition

Can I still log in to my illion account or the illion Public Access Centre?

No. There is no separate consumer illion login for your credit score any more. illion's consumer credit data has been consolidated into the Experian bureau following Experian's acquisition, so the consumer-facing illion sign-in and the illion Public Access Centre no longer act as the place to view or request your personal credit information. If you're searching for an illion credit score login, the equivalent today is your ClearScore account, which shows your Experian credit score and report.

What happened to the free illion credit report I used to request directly?

Australians still have the right to a free copy of their consumer credit report - that right sits in law and did not change with the acquisition. What changed is who you request it from. Requests that once went to illion are now handled through Experian as the bureau holding that consumer data. If you'd rather not wait for a posted or emailed statutory copy, you can see your Experian credit report on ClearScore straight away, for free, forever.

Do I need to sign up again to see the credit data illion used to hold?

If you already have a ClearScore Australia account, no - the data illion previously held now flows into the Experian credit score and report already shown in your account. If you don't have an account yet, you'll need to create one and verify your identity, which takes a few minutes and doesn't affect your score.

Where do I see the illion tab that used to appear in my ClearScore account?

It's gone, and that's intentional. ClearScore Australia previously showed illion as a separate score alongside Experian. Now that the two datasets have been consolidated, your account shows a single Experian credit score and report. Head to your report page and you'll find the same categories of information in one place rather than split across two tabs.

Was my illion credit history transferred to Experian, or did it start from scratch?

Your history was not wiped. The consumer credit information illion held - accounts, repayment history, enquiries, defaults and public record data - has been consolidated into the Experian bureau. You may notice your score looks different from the illion number you remember, but that's because Experian applies its own scoring model, not because your history has been reset. In Australia, both illion and Experian use a 0 to 1,000 scale.

Does illion still exist at all - and what about business credit reports?

The illion name still exists in the market for commercial and business services, including business credit reporting, data analytics and bureau products used by organisations rather than individuals. What has changed for consumers is that personal credit reporting is now handled through Experian. If you're looking for a commercial credit report on a company or a supplier, that is a separate service from the personal credit report you check on ClearScore.

How do I get a free statutory copy of my credit report in Australia now?

You can request a free copy directly from each credit reporting body - Experian and Equifax - usually once every three months, and always free after a refusal of credit or a correction. You'll need to provide identity documents, and the bureau has a set period in which to respond. Alternatively, sign up to ClearScore and view your Experian credit score and report immediately, with updates as your file changes and no cost at any point.

How did illion calculate credit scores?

In Australia, credit scores are calculated by credit reporting agencies based on information gathered from credit providers such as banks, credit card companies, and other lenders. Australia's three major credit reporting agencies were Equifax, Experian, and illion. illion has now been acquired by Experian, so the two main credit bureaus today are Experian and Equifax.

illion credit scores were calculated based on information provided by credit providers and financial institutions. That data now feeds into the Experian credit score shown on ClearScore Australia. Factors such as defaulting on loan, late payments, joint debts, and applying for too many credit products can lower your score.

How to check and fix errors on the credit file illion used to hold

Errors on a credit report can usually be corrected once they've been investigated, and it costs you nothing to raise a correction request. Because illion's consumer credit data has been consolidated into the Experian bureau, corrections that would once have gone to illion are now raised with Experian or directly with the credit provider that supplied the information.

Errors worth looking for after a bureau consolidation

• Duplicate accounts - the same loan or credit card appearing twice, which can make your total exposure look larger than it is.

• Incorrect credit limits or balances, particularly on cards you've closed or where a limit has been increased or reduced.

• Defaults or repayment markers that should have aged off your file, or that were paid but never updated to show as settled.

• Identity mismatches - a misspelt name, an old address, a wrong date of birth, or entries belonging to someone with a similar name.

• Enquiries you don't recognise, which can point to an application made in your name without your knowledge.

• Accounts closed years ago still showing as open.

Who you dispute with now

• The credit provider (your bank, lender, telco or utility) if the underlying information is wrong - they supplied it, so they're the ones who can amend it at source.

• The credit reporting body - Experian for the data illion previously held, or Equifax for its own file - if the report itself is showing information incorrectly or has failed to reflect an update.

• You can approach either one; they're required to consult each other where needed, so you don't have to chase both.

Step-by-step: raising a correction

• Get a current copy of your report so you're disputing what's on file today, not what you remember.

• Write down exactly which entry is wrong and what it should say - one issue per dispute keeps things clean.

• Gather evidence: statements, payout letters, settlement confirmations, or correspondence showing the correct position.

• Contact the credit provider or the bureau in writing, quote the account details, and keep a copy of everything you send.

• Note the date you lodged it and set a reminder to follow up.

• Once corrected, check your report again to confirm the change has flowed through.

How long a response should take

• Under Australian credit reporting rules, a bureau or credit provider generally has 30 days to investigate and respond to a correction request.

• They can ask for more time if the matter is complex, but they must tell you why and give you a revised timeframe.

• Corrections are free - no one may charge you for fixing an error on your credit file.

If your request is refused

• You must be given written reasons for the refusal, including who to escalate to.

• Take the complaint to the Australian Financial Complaints Authority (AFCA), which handles disputes involving credit providers and credit reporting bodies at no cost to you.

• The Office of the Australian Information Commissioner (OAIC) is the other escalation route, particularly where the issue concerns how your personal information has been handled.

Credit bans and suspected fraud

• If you believe you've been the victim of fraud or identity theft, you can request a free credit ban, which stops the bureau disclosing your file to credit providers.

• A ban runs for an initial period of 21 days and can be extended while the matter is investigated.

• Place the ban with each bureau holding your data - Experian and Equifax - so no lender can access your file in the meantime.

How quickly a correction shows up in your score

• Once an entry is amended, the bureau recalculates your score the next time your file is refreshed - often within days rather than months.

• Removing a default or an incorrect enquiry can lift your score noticeably; correcting an address or spelling usually won't move the number, but it does help lenders match you to your own file.

• Check your report again a few weeks later to confirm the correction has held and hasn't been re-reported by the original provider.

How to improve your credit score

To improve your credit score, you can follow ClearScore's recommendations by visiting ‘Reports’ and see your ‘Insights’ showing you the tips of how to improve your credit score, which may include paying bills on time, reducing credit card balances, and checking your credit report regularly for errors or fraudulent activity. Remember to check your credit score and report regularly to ensure that your credit history is accurate and up-to-date.

In addition, here are some more helpful tips to keep in mind:

• Regularly review your credit report for errors

• Pay bills on time (credit card dues, loan instalments etc). Set up payment reminders or auto-debit instructions

• Keep an eye on how much of your credit card limit you use (credit utilisation may be one factor in a score; its effect varies by bureau, lender and individual credit file)

• Apply for credit only when necessary (multiple queries in a short time can reduce your score)

How long it really takes to move up a credit score band in Australia

Moving up a credit score band usually takes months, not days. The advice that you can reach a 700 credit score in 30 days sets an expectation Australian credit reporting simply can't meet, because most of what drives your score is a record of behaviour over time. That said, 30 days is not wasted - a handful of things genuinely can shift inside a month, and knowing which ones is the difference between focused effort and frustration.

What genuinely moves fast

Three things can change your score relatively quickly. The first is credit utilisation: paying down card balances so you're using well under 30% of your limits can be reflected as soon as your lender reports the new balance, typically within a billing cycle. The second is pausing applications - every hard enquiry sits on your file for over five years, so simply not applying for anything new stops fresh damage immediately. The third is correcting errors; removing an incorrect default or an enquiry you never made can produce the single largest jump most people ever see, and it can land within weeks of the correction being processed.

What only time can fix

Depth of repayment history is the biggest constraint. Monthly repayment history stays on your report for two years, so a run of on-time payments needs months to accumulate into a meaningful pattern. Defaults sit on your file for five years, and bankruptcy for five years from the date you became bankrupt or two years from when it ends, whichever is later. Paying a default doesn't erase it - it updates to show as paid, which lenders view more favourably, but the entry stays. The single biggest killer of credit scores remains missed payments, precisely because their effect is measured in years rather than weeks.

Realistic band-to-band timelines

On the 0 to 1,000 Experian scale used on ClearScore Australia, moving from Fair (300-499) to Good (500-699) is the fastest climb for most people - around six to twelve months of consistent on-time repayments, low utilisation and no new applications, assuming there's no default holding you down. Building from 500 to 700, which crosses into the Great band, typically takes twelve to eighteen months, because it requires demonstrated history rather than the absence of problems. Reaching a 720-type score inside six months is realistic only if you're starting from the upper end of Good with a clean file. Great (700-799) to Excellent (800+) is the slowest stretch of all - often two years or more - since it rewards a long, unblemished history and settled credit management rather than any single action.

Why Experian and Equifax move at different speeds

The same repayment can lift one score before the other. Each bureau receives data from lenders on its own reporting cycle, holds a slightly different set of accounts depending on which providers report to it, and applies its own proprietary model with its own weightings. It's normal to see your Experian score respond to a change a few weeks ahead of Equifax, or for one to move further than the other on identical behaviour. Neither is wrong - they're measuring the same conduct with different instruments.

What Excellent actually requires - and when to stop chasing

An Excellent score in Australia generally reflects several years of on-time repayments, low and stable utilisation, few enquiries, and a mix of credit handled without incident. There is no 1,000-point universal target to chase; the scales differ by bureau, and lenders set their own cut-offs anyway. Past the point where you comfortably qualify for the products and rates you want, extra points bring diminishing returns. Your score refreshes as lenders report new information - most commonly monthly - so checking it every few weeks is enough to spot changes and errors without becoming a daily habit.
